SELF-LOADING CART.

j I Specifica tion of Letters Patent No. 12,562, dated March 20, 1855.

A. SruAcun Cart 1; and weldoj hereby declare that the following is afull and exact description thereof, reference being had to theaccomfpanying drawingsfand to the letters of refqerencemarked thereon. aI j Our inventionfconsistsof a largescoop or scraper A, of sufficientdimensions to hold a cart load of earth, more or less, con- Istructed ofiron andfsteel or any suitable w material and dividedw transversely alittle back of the centerandthe two parts joined to each other byithehinges B, Eat the upper innerl corners of the sides andby a a springhook O, and catch under thev bottom, f itbeing so divided andlputtogether for the gpurpose of dropping'the load through the bottom by itsown weight when the hook O, is; disengaged froml the catch. ,The saidflscoop A, is"suspended,under an-ordinary cart by the four chains D, D,D, D,I which pass overthefipulleysE, E, E, E, ;on the cart shafts and'wind around the Iwindlass :shaft F, placedbetween and parallel with a fthe saidcart shafts and which is turned by the crank G,by amanstandingbehind, and

by whichmeansthe scoopwhenfilled may, be elevated to admit of its beinghauled away and discharged, which is done by disengaging the spring 0,which allows the two parts of the bottom to separate and the load falldown between them, without stop ping the horse, whenfthefdriver byforcing down the lever H closes again the twoparts of the scoop whichare retained by the {spring hook andcatch.

On the underside of the cart shafts near their forward ends are placedthe angle jfirons J, to which the chains from an extra ,Qfteamused toassist in loading said scoop,

are attached, and from; Which chains or ropes run back to the scoop,bywhich means the draft of the extra team is combined with the force ofthe horse thecart, and

alsofthe draft upon the scoop lowered and i brought nearer a horizontalline, and also the pressure upon the back of thehorse in the cart, fromthe draft of the extra team, materially relieved and lessened.

Themanner of operating our invention is as follows: The ground beingplowed the scoop cart is brought upon it to a suitable place when anextra team is hitched in being lowered to the ground and guided in bythe handle or lever H, the extra team and the horse in the cart aredriven forward in concert about six feet which is generally suflicientto fill the scoop; the extra team is then detached, and stands stillwhile the scoop is elevated and driven away and another brought into itsplace, when the extra team is again hitched on, and so on in succession,by which the extra team serves to load a given number or gang as theyseverally arrive, and by which the said extra team in assisting toloadthescoop, does the work virtually of a large number of shovelers.

We do not claim the combination of a large scoop or scraper (undivided)with the ordinarycart, by suspension in such a manner, that the scoop orscrapper may be raised or lowered by a Windlass or lever for thishasbeen done before; neither do we claim dividing the scoop transverselynear the middle as such a device has been known and applied in dredgingmachines.

What we claim as our invention and desire to secure by Letters'Patent isl, The combination of a large divided scoop constructed as described,with an ordinary cart,,in the manner and for the pur- "UNITED STATESPATENT OFFICE.
